IMPROVEMENT IN PRIMERS FOR CARTRIDGES. I

Specification forming part of LettersPatent No. 120,196, dated October 24, 1871.

To all whom it may concern:

. Be it known that we, ALFRED. CHARLES Bonus and JEROME ORCUTT, of Bridgeport, in

Primers for Cartridges, of which the following is aspecification, reference being had to the accompanying drawin Our invention relates to an improved primer for cartridges 5 and consists in an ordinary per cussion-cap having a circular disk inserted ed'ge wise therein as an anvil, the anvil being secured by nioking or bending down the edge of the cap.

Figure l is an inside end view of our primer. Fig. 2 is a perspective view of the primer, and Fig. 3 is a longitudinal section of the same.

The object of our invention is to produce a simple and reliable primer, which may be made complete by machinery without the aid of hand labor.

We are aware that various forms of anvils have been heretofore inserted into percussioncaps to form primers; but owing to the irregula r shapes of the anvils they could not be inserted in the proper positions with any degree of certainty by machinery and consequently they were required to be put together by hand, which rendered them quite expensive. This difficulty we obviate by using as an anvil a circular disk of metal inserted edgewise into the cap.

in the drawing, A represents an ordinary percussion-cap, and B the circular disk anvil, which is made of the same diameter as the cap, and inserted edgewise therein, so as to bear against the back end, as shown in Fig. 3. The anvil is held in place by nicking or bending down the edge of the cap on each side of it, as shown at the points a a in all the figures. As this anvil is a disk of the diameter of the interior of the cap it is obviousthat it must be held on edge, as well as held in the cap; and this is effected by the nicking of the cap, as represented in the drawing. It will be seen that a small portion of an y particular side foremost; and, therefore,

are able by. machinery to insert them in are proper position with perfect certaii'ity and contscquently we can produce our primers more rapidly and at much less cost than those now in common use.

The primers lllrldG'Oll our plan can he used in any cartridgeshell having a recess to receive the cap and a support for the front edge of the anvil to bear against.

Our primers are cheap, simple, and reliable; the anvil is so fastened that it cannot be lost out and so shaped as to insure the ignition of the iuhninate, and to leave a free passage for the flame forward tl'lerefroni. The anvil being so curely fastened in place, as described, renders the ,primers especially suitable for transportation and for the use of sportsmen and others having reloadable cartridges.

Having described our invention, what we claim 1sl. A disk-shaped anvil inserted edgewise into a percussion-cap, substantially as and for the purpose set forth. 7

2. The method of securing the anvil lB upright within the cap and holding it therein by indenting or nickin g the edge ot'the cap and compressing it againstthe anvil, substantially as described.
